Hi everyone, newbie here. I am interested in upgrading early to the new iPhone when it comes out (assuming it's a "5" and not a "4S"). I have tried to read up on here but there's no guide to this but I know folks do this so I am seeking your advice and guidance. So I sell my iPhone 4 and use a temporary phone before I get the 5. 1. How can i get a regular SIM that would have my number to fit in the other phone - call AT&T? 2. Do I need to do anything at this time regarding my line's account(assuming the iPhone ships in less than a month after release)? 3. When the 5 is announced and I'm ordering it - is there an option for current owners who want to upgrade so I can just maintain my number? How do I ensure I maintain my number? 4. Assuming 3 above is not possible, do i just order the 5 with another number and pop in my microSIM? (but this means a new account....?) 5. Is there anything else I have missed? Thanks in advance!
